// were dynamically loaded with the RTLD_GLOBAL flag.
RTLD_NEXT Handle = Handle{unsafe.Pointer(uintptr(C.rtld_next))}
// Find the next occurrence of the desired symbol in the
// search order after the current object. This allows one
// to provide a wrapper around a function in another shared
// object, so that, for example, the definition of a
// function in a preloaded shared object (see LD_PRELOAD in
// ld.so(8)) can find and invoke the "real" function
// provided in another shared object (or for that matter,
// the "next" definition of the function in cases where
// there are multiple layers of preloading).
